Description
Technical field
The present invention relates to a kind of mine filling consolidating material and using method thereof, belong to
buildbuild field of material technology.
Background technology
Along with the quick growth of resource requirement in world wide, the serious harm that the refuse of the exploitation generation of mineral wealth and worked-out section are brought environment and safety.In order to green and safe working, mining with stowing technique improving resource recovery rate, prevent big area geologic hazard, guarantee manual security etc. in advantage further highlight.In the development engineering of mine filling technology, consolidating material is of paramount importance factor in Cut-and-fill Mining Technology, and the change of consolidating material causes the change of mining methods sometimes; Jointing compound, as one of the main raw of cemented filling material, occupies critical role in filling in mine mining technology.
Due to traditional a large amount of cement of packing material consumption, greatly improve production cost, and intensity not easily reaches standard-required.Therefore, the application and development of filling mining technique is seriously constrained.In order to obtain good filling quality, we should consider to adopt new technology, new technology, and when not reducing obturator intensity, reduce cement unit consumption amount or seek cement surrogate, this is also the main direction of filling technique.
Summary of the invention
The object of the invention is to: provide one to replace cement, and when do not reduce fill intensity, reduce costs meet the mine filling consolidating material and using method thereof that filling in mine requires.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of mine filling consolidating material, composed of the following components: breeze 20-40 part, kerosene shale ash 30-60 part, oil refining desulfurization slag 20-50 part, exciting agent 0.1-10 part; Described part is weight part;

The present invention adopts different grades breeze to test, and when other raw materials, proportioning, technique are identical, breeze higher grade, and the time of coagulation of prepared consolidating material is shorter, but cost also corresponding raising.In order to meet time of coagulation require while reduce costs, preferably, described breeze is S95 level.
The present invention adopts different sorts exciting agent to test, and when other raw materials, proportioning, technique are constant, the quality of exciting agent is better, and the time of coagulation of prepared consolidating material is shorter, but cost also corresponding raising.In order to meet time of coagulation require while reduce costs, preferably, described exciting agent is Sodium sulfate anhydrous.min(99).
The using method of mine filling consolidating material of the present invention, mixes mine filling consolidating material of the present invention by cement-sand ratio 1:8 with sand, then adds water, and makes the mine filling slip of mass concentration 70%.Its presetting period, final setting time was at 50-135min at 30-110min; 1d ultimate compression strength is at 0.3-2MPa, 3d ultimate compression strength 3-9MPa, 28d ultimate compression strength 4-11MPa.
beneficial effect of the present invention is:
1. the kerosene shale ash that the present invention uses is the industrial waste after oil shale distillation or burning, containing 50-65 part SiO
2, 12-20 part Al
2o
3with 6-10 part CaO, apply in material of construction for it and provide theoretical foundation.Utilize kerosene shale ash to replace cement to prepare mine filling material not only to contribute to saving natural resource; reduce costs, utilize protection of the environment in addition, obtain good economic benefit and social benefit; to development China recycling economy, alleviate Mineral Resources in China shortage etc. and there is strategic importance.
2. the byproduct that the oil refining desulfurization slag that the present invention uses is refinery desulfurizing combustion.At present, major part is all used as the material filling out sea, and only has small portion to be used as the additive in cement mill.Prepare mine filling material with oil refining desulfurization slag replacement lime and gypsum, not only can solve the whereabouts problem of oil refining desulfurization slag, huge economic benefit can also be created, mine filling material produce cost is significantly reduced.Therefore, desulfurization slag mine filling material of refining oil has broad application prospects.In addition, oil refining desulfurization slag contains 48-60 part CaO and 33-43 part II type anhydrite, and the mine filling material prepared with oil refining desulfurization slag replacement lime and gypsum, just substantially can complete hydration heat in 2min, temperature can reach 90 DEG C, thus obviously reduces the presetting period.
3. exciting agent makes the anhydrite dissolution rate in oil refining desulfurization slag obviously accelerate, and time of coagulation significantly shortens, and hydration rate is accelerated, and hydration temperature raises, and the heat evolution velocity of anhydrite is accelerated greatly, and the gain in strength of hardenite is very fast; Exciting agent increases the basicity of system, accelerates Vitrea dissolving in breeze and kerosene shale ash, improves reactive behavior.
4. desulfurization slag of refining oil not only increases the basicity of system, also improves the temperature of system, greatly accelerates the reactive behavior of breeze and kerosene shale ash, makes the performance comparatively early of its chemically reactive; Anhydrite and breeze, kerosene shale ash hydration reaction mutually promote (presetting period is short, intensity is high).
5. to have time of coagulation short for the fast hard consolidating material of the present invention, and the features such as early strength is high, and contract with dry rate is little, later strength not retraction, have a wide range of applications at mine filling Material Field.
